"pela"

we have Puerto Ricans in the forum, can't you enlighten us, guys?

anyway, I find interesting to try... we all agree about "gas". as to "pela", I was going to suggest it's in Spanish a form of "peel" or the result of something peeled, but in the DRAE "pela" appears also as a synonym of 1) "peseta" (Spanish coin) and 2) of "paliza" (in Cuba, Panama and Puerto Rico...). I looked it up in a dictionary of Spanish varieties, www.jergasdehablahispana.org, and found that "pelar" (v.) is also not to care about somebody or something: "me la pela" (= I don't care), a phrase I had heard in a song from the Spanish group Estopa (and just now I find what it means!). in Argentina, "pelar" means also (vulgar) to undress the male organ...

I am not a Puerto Rican but I looked for the entire lyrics of the song. I had requested earlier to post more context and this was quite interesting, so, I surfed the net for the lyrics.
Apparently "gas" refers to something that can really "skin, pull your hair off, peel" your skin off or some part of your body.
From the song, you can either think that they are dancing in a club/disco or so and the gas, you know the one you are usually dancing and kind of comes out ( I haven't been to any in ages but I see the stuff in the movies, hahaha), ok, so that gas is going to be really strong and it will have a stronger effect than the usual one. This is reggeaton, this could be anything related to this, ****, or ***. So, imagine what the gas can do...can take your skin off, heavy stuff...

It's a puerto rico expression (used only there) that means something like this:
When you do something bad to someone else, probably that one will do the same to you; when you're waiting to see what's goin'on with this one, you are waiting to see if the Gas Pela...in spanish something like "dejalo a ver si el gas pela o no pela", in english "let's see if the fire burns or not". Let's see what happens.

Don't know if i've let you understand what i mean.

The origin is this: in Puerto Rico the gas for torches was sold individually and people who bought it used to bring their own cans to store it, but this kind of gas was quite strong and if it touched your skin it peeled it.

It's the better i've found out and the link to the original explanation is here:
